PROBLEM TO BE SOLVED: To provide a system of treating ship ballast water, which is compact, does not require much electricity, and facilitates controlling of the concentration of a disinfectant.SOLUTION: The system of treating ship ballast water includes a water intake 1 for taking in raw water W, a main line 2 which is connected to the water intake 1 and supplies raw water W, and a ballast tank 3 disposed on the terminal of the same. In the middle of the main line 2, a first liquid-feeding pump 4 is disposed as a water-feeding means. On the downstream side to the first liquid-feeding pump 4 of the main line 2, a bypass line 5A is annexed The bypass line 5A is provided with a disinfectant dissolution tank 6 filled with a dichloroisocyanuric acid S. The disinfectant dissolution tank 6 keeps a bypass line 5B connected, the terminal of which is provided with a disinfectant solution storage tank 7 is connected. A bypass line 5C is connected to a disinfectant solution storage tank 7, and the bypass line 5C joins the main line 2. |
